BONE REPAIR BY ELECTRICITY
October 29, 1971 - Pennsylvania, USA
The first successful use of electricity to repair a bone fracture is reported by surgeons at the University of Pennsylvania. Electrical currents have been used to heal bone since the mid-1800s, and the effect of electrical stimulation on bone has been long studied and well documented.When human bone is bent or broken, it generates an electrical charge ("On the Piezoelectric Effect of Bone", Fukada and Yasuda, 1957). This low level electrical charge stimulates the body's internal repair mechanism.
FIRST BALLPOINT PEN
October 29, 1945 - United States
The first ball point pen in the U.S. went on sale at Gimbels Department Stores for $12.95. In June, 1945, Chicago businessman Milton Reynolds, in Buenos Aires on unrelated business, saw the Biro pen in a store, recognized the pen's sales potential and bought a few as samples. Reynolds returned to America and started manufacturing. He copied the product in four months, (ignoring the patent rights of the Argentine manufacturer, Eversharp Company. On the first day of sale, his Reynolds' Rocket pen was immediately successful; $100,000 worth are sold its first day on the market). The ballpoint pen became a fad. However, it leaked, skipped and was unreliable. By 1948, the price dropped to less than 50 cents. Reynolds' company failed in 1951.

But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen.
